Note : I advice you to edit your Css file at the end, later that will be easier to find and correct it.
To learn more about Css code and their properties, I invite you to read this source,

This zoom is a feature from your template, so I can't really tell you how to process to disable it... I can invite you to contact your template creator.
Hope that will help you.
Regards,
